Power USB

The USB+Power interconnect system was developed by AFCI to enable additional power to be delivered to peripheral devices connected using USB 2.0 cable links. When compared to a standard USB connector, the USB+Power connector interface includes four additional contacts for power delivery, each rated at 5A/contact, to supplement the connector’s current-carrying capability.

For many devices, this eliminates the requirement for a separate power source reducing the number of cables required. For peripherals not requiring the additional current, the USB+Power receptacle will mate with a standard USB ‘A’plug.

To ensure proper mating, USB+Power is individually keyed and color coded for 5V, 12V, and 24V.
